Solution Strengths, Weaknesses and Critical Indicators

Anaerobic Digester Associated Technology:

NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.


  • Long usable life and can be run reliably
  • Creates energy and generates environmental credits
  • Requires proper preparation of the feedstock
  • Requires other technologies for energy utilization
  • Requires other technologies for digestate handling
  • Proper feeding & system monitoring is required to avoid system downtime
  • Proven technology for odor control, GHG reduction and pathogen reduction

Newtrient Comments/Opinions:

Engine/Generator Technologies:

  • Produce electricity for on-site use and sale to the grid with a Utility Power Purchase Agreement (PPA)
  • Produce heat which is used on site to increase digester influent to proper temperature
  • Proven technology for use with biogas
  • Require scrubbing of hydrogen sulfide from biogas for best performance
  • Require regular maintenance and monitoring
  • Require specialized safety equipment
  • Require a utility interconnect if power is sold to the grid
The Dressor-Rand Guascor engine is widely utilized in the biogas industry. This engine is supplied and supported by many different packagers, suppliers and distributors and these systems can be found on dairy digestion systems across the United States. These are reliable, proven performers that, with the proper maintenance, can provide years of service.
